A few weeks ago, I went over\xa07 of the most important longevity biomarkers\xa0to track. Today, I\u2019m shifting gears a bit. The theme remains longevity markers, but the markers I\u2019ll discuss today are\xa0subjective, logistical,\xa0and\xa0psychological\xa0ones. A couple involve physical sense but you can\u2019t measure these with a blood draw or a lab scan. The only way to assess your standing is through some genuine self-experiment and honest soul-searching. Or by, in one case, running a mile.
